I would recommend Debian. It's well-documented, in these days easy to install and extra packages are very easy to install. It won't install anything you don't need, so no open ports without reason. It doesn't come with a graphical system by default, which is probably good for you because you want a ftp server. I'm almost 100% sure Debian supports your hardware.Originally Posted by z969307
